Semantic Coherence: DESCOVY (Gilead Sciences) – Signal Evidence & AI Readability

Semantic Coherence — The Lens

Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.

Semantic Coherence Homepage promise vs. Sub-page reality.

There is virtually zero semantic drift between the homepage signal and sub-page substance. The homepage H2 and H6 tags promise efficacy results from a ‘2-year study,’ and the ‘clinical-trial-efficacy-results’ page delivers exactly that, including specific comparative data on Bone Mineral Density (BMD) and renal labs. The transition from high-level efficacy to cost support ($0 per month) is logically consistent and supported by details on the Gilead Advancing Access program.

Semantic Coherence is read from the heading hierarchy first: what each page announces in its H1 and headings, then whether the body actually delivers on it. Below is the structure the engine mapped, followed by the clean text to check for drift between promise and reality.
